VAPORIZER.

appncatinn'md August 1a, 1923. serial No. 657,25*?.

To all whom t may concern.' Y

, Be it known that I, ALBERT F.=DAYTON,

a citizen of fthe United States, and a resident of Pleasanton, county ofAlameda, State of California, have invented a neuT and useful Vaporizer,of which the' following is a specification.

This'invention relates to vaporizers for liquid fuel burners andparticularly to burners designed for use in connection with steam-drivenautomobiles or othergvehicles, and has for its primary object theprovision of a device of this character which can be easily and quicklycleaned as the occasion requires.

A further object of the invention is to provide a vaporizer of thischaracter which will operate to maximize vaporiz'ation of the fuelbefore it reaches the burners of theJ heating system with which igt isemployed, and to so construct and design the invention whereby avaporizingarea of maximum proportion may be arranged in a space ofminimum size( 'fr A further object of .the invention is to provide avaporizer whose characterizing features act to insure perfectvapbrization of the fuel and to accommodate an excess supply of gas andpermit said supply to be drawn upon in a manner to induce and maintainsteady pressure on the; burner nozzles and a fiame of uniform size.

Another object ofV the invention resides in the provision of a vaporizerwhich can ybe entirely removed `from its Vco-acting burners and boilerstructures respectively and instantly reapplied thereto so" that thevaporizer may be always kept inja clean working condition, free fromcarbon deposits which would otherwise acti to clog the device andprevent the free Aflow of gas to the burners.

A still further object of the invention is to provide a vaporizer thatcan be quickly arranged in a liquid fuel burning system of well-knowndesign and which, when necessary, can be removed from the system and anew vapo-rizer substituted 4.therefor at small cost and withoutrequiring'fthe skill of an expert mechanic.

My invention, therefore, comprises cer tain novel features ofconstruction and arrangement and combination of `elements hereinafterset forth and pointed out in the claims annexed hereto.

In the drawings, Figure l is a perspective view of the vaporizer,`lifigure 2 is a vertical longitudinal section therethrough showing itsapplication to a fire-box, and Figure is a transverse section taken onthe line 3 3 of Figure 2.

As herein stated, my invention is particularly designed for use inconnection with liquid fuel operated vehicles of the steam driven type.This, however, is simply illustrative and shall not be taken as anunnecessary limitation of the invention as it is capable of being usedin connection with any well-known form of fuel burner. I mention itsparticular adaptability to mechanisnis of the above mentioned typebecause of the ease with which the vaporizer can be removed when it isdesired to clean same of carbon deposits or foreign sediment. Its designpeculiarly adapts itself to steam-driven vehicles because of thedispatch with which the invention can be removed as desired withoutrequiring the aid or assistance of a skilled mechanic, and furtherbecause of the facility with which the invention can be removed as theoccasion requires and later readjusted to the burner system without inthe least way impair-ing the latter.

I will therefore refer to A as a conventional fire-box of the typeemployed in connection with the-boiler of a steam engine. This fire-boxis provided with a fuel vaporizer (5) which includes in its constructionan outer tube or pipe (6) and an inner tube (7). The outer tube. extendsthrough the fire-box and beyond the sides thereof and one end of thetube is closed -by a removable cap (8). On the outside wall of the boxand in contact therewith is a stop shoulder (9) formed as a fixed ypartof said tube (6). The opposite end of the tube is connected with a fuelinlet pipe (10) which leads from a source of supply, not shown.Generally this source of supply in- `cludes means whereby liquid fuelunder suitable pressure may be fed to the burners of a heating system.In the present instance, liquid fuel from the supply is conducted to thetube (6). The tube is disposed in the fire-box so that it is made tooverlie the usual burners. It acts in the fashion or manner of anoverlying retort and is so subjected to the action or heat of the flameas to cause proper vaporization Vof the oil as the latter is fed fromits source of supply. v Y 4 The inner tube (7) is preferably" formed ofcopper or other suitable heat-retaining material and illustrated thistube is closed at one end as at (11) and open at its otliei end (l2).This provides the tube witlia gas chamber wherein excess gas may beaccommodated to insure a steady condition of the flame at the burners.his chambei' acts to establish a rreserve for the gas and accordingV tooperations of the burners this i'esirve can be drawn upon withconsistency and to the extenttliat a uniform pressure isf` One end lofthe.`

maintained' at the burners. tube (7) faces in the direction ofcap (8)and same is formed with an internal thread (13). Then it is desired toremove the tube (7) or core. soto speak, ,the cap (8) is taken ofi' ofthe outer tube (6) and a suitable tool or threaded rod, not shown, isinserted in said tube (G) and manipulated so as to cause it to engagewith the aforesaid thread (13).

will be withdrawn therewith. 1t can then be immersedin4 a cleansingbath, such as gasoline or the like, or scrubbed or otherwise suitablywashed in order that sediment, sandzand carbon deposits can be removedtherefrom. When this is accomplished the said tube (7) can be readjustedto its'foriner position. All of this may be -accomplished with dispatchandfwitli utmost ease and convenience.

In order that the fuel, as it enters the tube (6)y may be made to takemaximum travel around the tube (7) or between same and the outer tube(6),y and further with a view of thoroughly disintegjratinpthe fuel, Iprovide said tube (7) with aiiexternal spiral thread (1 4). This extendspreferably throughout 4the length of the tube and the windings of thethread or convolutions are proportioned to come snugly in engagementwith the inner walls of the tube Inv this manner and according` to'theprecise spacing' apart ofthe windings ofthe thread (14) 1 am able tocause a maximum circu-4 lation of liquid fuel ovei' a minimum arxamandat the same time linsure proper 'vaporizatioii of the fuel before ita gas to the burners.

The outer tube (6) is-provided with a lioll i y r -an external threadembracedrbyf the walls lof the tube to constitute therewith a. mixingAlow head (15) arranged in open communication with the tube (6) by way ofthe perforations (16). This head supportspipes.

(17) from which the usual b urners .(18) are hung.

By drawing' in`r an outwardv `directionupon the tool, the said tube (7)is delivered f as These burners extend into the fire-box so that thefiame produced thereby will be made to impinge against the Vapor-12913:' .is if Fromv the'f foregoing. desc pltion 'it obviously followsthat a novel form of vaporizei' is Vprovided wherein, the parts thereofVare freely separable in "order that these parte may be set up; orknocked down as the occasion requires, and that these parts are :sodesigned and constructed that they may be conveniently installed in thefire-box of a burner system' 'without' requiring anyV elaborate orAcostly alteration 'in the conlsti-notionthereof: i1 L ff l.
